Category DIFFRN_MEASUREMENT

Name:
'diffrn_measurement'

Description:

   Data items in the DIFFRN_MEASUREMENT category record details
   about the device used to orient and/or position the crystal
   during data measurement and the manner in which the diffraction
   data were measured.

Examples:

Example 1 - based on PDB entry 5HVP and laboratory records for the structure corresponding to PDB entry 5HVP.
